@cindex PowerPC architecture
When @value{GDBN} is debugging the PowerPC architecture, it provides a set of
pseudo-registers to enable inspection of 128-bit wide Decimal Floating Point
numbers stored in the floating point registers. These values must be stored
in two consecutive registers, always starting at an even register like
@code{f0} or @code{f2}.
The pseudo-registers go from @code{$dl0} through @code{$dl15}, and are formed
by joining the even/odd register pairs @code{f0} and @code{f1} for @code{$dl0},
@code{f2} and @code{f3} for @code{$dl1} and so on.
